(Look in the upper right corner of the page to find a link to the “Subtraction” workbooks.) The workbooks are in pdf format so you can save them to your computer and print them out to do offline.

This is a fabulous resource to enhance any study of mathematics! Bookmark it to return often.

This is one of the most innovative math sites I’ve seen. A Canadian mathematician/teacher developed this site to help classroom teachers address the multiple math skill levels of students through challenging and engaging activities and games that are demonstrated on videos. All of it can be tweaked for use in the homeschool environment.

When you get to the site, you’ll see a menu and some of the featured videos. The videos are designed for teachers to view in preparation for teaching a classroom lesson. Look for the Grade Range Menu and click on the grade levels of interest to you that include:

*7-9 – Enjoy a game of “Integral Fission,” practice subtracting fractions, engage in cipher breaking, strategize, practice squaring and cubing, do puzzles to learn about bases, exponents and polygons, memorize the formula for the area of a cone, find out what Archimedes knows about the area and volume of a sphere.

*10-12 – Play games and solve puzzles that teach algebra, scientific notation, Pythagoras’ theorem, physics, trigonometry, and learn a little calculus through song.

Click on any topic and a new page opens where you can watch a demonstration video. Many of the activities also come with free downloadable worksheets and solutions as well.

You will also find curricula and puzzle books for sale on this site, but you don’t have to purchase a thing to access the incredible range of free math activity videos. Bookmark this site to return often.

This ad-supported website features a smattering of free interactive math lessons, printable worksheets, games and more to help students in about grades 5-8 learn math. Gifted younger children and remedial older students may benefit from the resources provided as well.

The site was designed by a math teacher who also developed a complete math course that is available for sale on the site. However, you don’t have to purchase a thing to access the generous sampling of math lessons and materials.

When you get to the site you’ll see a brief introduction followed by some featured items and lots of advertisements. Look above the introduction for the horizontal menu that includes:

*Lessons – Learn how to determine the perimeter and area of polygons. Find out how to simplify, compare, order, and convert fractions. Explore decimals and percentages. Find out how to write algebraic expressions and equations and much more!

*WebQuests – This terrific resource provides math inquiries and instructions that lead to online explorations to find information and solve problems. Choose from a short but meaty selection of quests to recommended websites and learn about exponents and scientific notation, integers and science, math and climate, math and sports, number theory, percentages in daily life, and even a “Pi Day” celebration.

*Games – An assorment of interactive math games. Not all of the games featured here are open for free play. The ones that were accessible included: Factor Tree Game, Integer Football, Percent Goodies, and Probability Goodies.

This ad-supported website is sponsored by the same folks who created some of our favorite science sites for kids such as Chem4Kids.com, Biology4Kids.com, and Physics4Kids.com. It offers a wide variety of free, engaging games to help kids learn and practice a variety of math strands.

When you get to the website you will see an icon menu. Click on any one and a new page opens that contains an introduction to that math strand and, on most pages, a few recommended activities.

It may be less confusing and simpler to select activities from the home page that are featured under the following sections:

You can also use the the “Site Map” link (near the top of page) to instantly see and access the lessons and activities contained in each section. Regardless of how you explore the site, bookmark it to return often.

NOTE: This is an ad-supported website with randomly generated ads that if clicked on, will lead to outside websites that I have NOT reviewed. PARENTS, AS ALWAYS, SHOULD PREVIEW THE SITE AND SUPERVISE USE.

The title of this site is intended to get your attention and resonate with how you may feel about math, and not meant as an insult. It has been designed to help clarify some of those math concepts that cause confusion when it comes to algebra, geometry, trigonometry, and pre-calculus. It is assumed that you know some of the basic concepts, and that you want to reinforce or review them.

You’ll find free tutorials, sample problems, and quizzes along with interactive resources to help you learn:

*Geometry – Includes: Parallel Lines, Congruent Triangles and Right Triangles, Isosceles and Equilateral Triangles, Quadrilaterals, Parallelograms, Similar Polygons, Circles, Coordinate Geometry, Area and Volume of Solids, and “Computer Fun” which is described at the site as follows:

“For all you computer nerds our there, we’ve included a section full of short QBasic programs that do basic geometry problems. Feel free to download them, use them, and improve them (they’re freeware)!”

The site also provides a “Message Board” where you can ask for help when you need it, and a “Formula Database” that lets you easily access commonly used formulas and equations. Plus you can take quizzes to test your knowledge of various concepts. They also offer a nice selection of links to terrific math sites on the Net.

How big is a million? What comes after a trillion? How many atoms are in the atmosphere? Is there such a thing as a zillion? What is a googol? If it has to do with big numbers, this website explains it all.

When you get to the site click the “Continue” button. A new screen will appear that gives very basic instructions on how to explore the site. Take their advice, but the minute you have a question, or don’t understand something – click on the “Help” or “About Big Numbers” buttons at the bottom of your screen. If you never have a question – read it anyway as it will help you to understand the enormity of what the site is trying to accomplish, and provide you with some interesting information about big numbers and scientific notation. Don’t miss the “Odometers – A Simple Way of Grasping Big Numbers” article in the “About Big Numbers” section. Then, go back to exploring each page. Not only will you learn some amazing facts like how many kernels of wheat have been produced on Earth, and the area of our galaxy in square miles, and the total number of atoms in the universe – but you will begin to grasp what a really big number means.

The author of the site says to explore each page. Do it. You won’t be disappointed. There isn’t a table of contents for the site, and if you miss a page, you may miss important stuff like “The Table of the Names of Big Numbers” which is a great tool to print out – or you might miss an exercise to determine how small the universe would be if you could compress it. This is fascinating stuff! Even people with math-phobia will enjoy what is presented at Big Numbers – but remember, you should definitely explore each page to get the full impact of what this site has to offer. Have fun!
